so i think i got this pricing thing figured, 2nd wedding cake. please tell me what you think.

she wants the attached pic all 4 tiers minus the ribbon and pins, the tiny flowers in a turquoise with white centers and the dots white, the borders around the cakes she wants alternating white and turquoise dots.
cake sizes:
6
8
10
12
i charge for all tiers and give them a coupon for a free small 6inch anniversary cake on their anniversary. also delivery is free and it is about 30 miniuts away.

per Wilton 130 servings
i charge $3.00 per serving for fondant $390 plus $30 for the component set and miscellanies things. i then gave her 15% off as i was running a special at the time for bookings.
so her grand total was $347

so the verdict did i do good or bad on pricing?

I think you did just fine
